Desulfurization of Other Gases

Carbon dioxide may be desulfiuized with zine oxide at the same operating conditions as for hydrocarbons. Below about 150°C, however, zinc carbonate is also formed at temperatures below about 150°C but this is subsequently converted to zinc sulfide until saturation is reached. 

Hydrocarbons are converted into a mixture of hydrogen and oxides of carbon by reaction with steam over steam reforming catalysts. The reforming reaction is endothermic and the catalysts are packed into narrow tubes, which are heated in a furnace. The reforming furnace is commonly known as a reformer. An efficient methane steam reforming process was developed by 1936 and was first used on a large scale in North America during World War Two as shown in Ta-
